Best answer
Right option is (b) Electrical origin

Easy explanation: Magnetism is of electrical origin. The electrons revolving in an atom behave as tiny current loops and these current loops give rise to magnetism. An electric current produces a magnetic field. This magnetic field can be visualized as a pattern of circular field lines circling a wire.
